Why is moisture measurement critical in lithium-ion battery manufacture?
lithium-ion battery manufacture
Cleanliness is essential to the production process of Lithium-ion batteries, particularly for the anode and cathode coating, which needs to be carried out in two separate clean rooms as the materials cannot be allowed to come into contact with each other. The electrolyte filling must also be performed in a dry environment to prevent the Lithium Hexafluoride reacting with water vapour in the air to form Hydrogen Fluoride. Most manufacturers will carry out the entire assembly process in clean & controlled environments
As a general rule the ambient air in the production environment needs to be drier than -30 °C dew point (or 1.4 %rh at 23 °C).
